论文应用区域自动气象站2007-2008年逐时气温观测资料,分析了济南城市热岛的时空分布特征,结果表明,无论春、夏、秋、冬,济南的城市热岛在空间分布上均以泉城广场、市政府为中心呈环状放射发展。热岛强度以冬季最强,秋、春季次之,夏季最弱。对城市热岛进行小波分析发现,济南冬季和夏季城市热岛的主要振荡周期是以准24h为代表的日变化和准270h所代表的旬变化为主。夏季日变化不如冬季明显,夏季旬变化略强于冬季。济南城市热岛以日为周期呈规律性变化,城市热岛强度表现为夜间强,白天弱。
論文應用區域自動氣象站2007-2008年逐時氣溫觀測資料,分析瞭濟南城市熱島的時空分佈特徵,結果錶明,無論春、夏、鞦、鼕,濟南的城市熱島在空間分佈上均以泉城廣場、市政府為中心呈環狀放射髮展。熱島彊度以鼕季最彊,鞦、春季次之,夏季最弱。對城市熱島進行小波分析髮現,濟南鼕季和夏季城市熱島的主要振盪週期是以準24h為代錶的日變化和準270h所代錶的旬變化為主。夏季日變化不如鼕季明顯,夏季旬變化略彊于鼕季。濟南城市熱島以日為週期呈規律性變化,城市熱島彊度錶現為夜間彊,白天弱。

Based on the hourly temperature observed by automatic weather stations during 2007-2008, the temporal and spatial distribu- tions of urban heat island (UHI) in Jinan city were analyzed. The results showed that in four seasons ,the UHI intensity centered on the Spring square and city council and decreased around. The UHI intensity in winter was the strongest all the year round. Then, it was autumn and spring. The UHI intensity in summer was the weakest. The Morlet wavelet transform revealed that the UHI intensity had a temporal structure of diurnal (24h) and ten-day (270h) periods whether in summer or winter. The diurnal (Ten-day) periodic oscillation was weaker (stronger) in summer than winter. The UHI intensity was stronger in nighttime than daytime.
